TRACTION PRESSURE CONTROL SYSTEM

摘要

Input and output speeds of a traction gear transmission are measured to provide an actual speed ratio to be compared with the setting of the transmission drive ratio control for determining the slip of the traction gear elements (100, 108) through a data processing network (40 min ). This computed actual slip is compared to optimum slip conditions that are empirically determined and stored in the data processor for controlling operation of a servo (36 min ) continuously adjusting the contact pressure. The invention is described with reference to its application to a cone and roller type transmission system.
